In addition, the same or corresponding components are denoted by the same reference numerals regardless of the reference numerals, and redundant description thereof will be omitted. For convenience of explanation, the size and shape of each constituent member shown may be exaggerated or reduced have.

FIG. 1A shows a front view of a drilling apparatus 100 and a cross-sectional view of components according to an embodiment of the present invention. The inner side view of the drilling apparatus 100 is shown on the right side with respect to the dotted line Y-Y 'crossing the center of the drilling apparatus 100 and the front view seen from the outside of the drilling apparatus 100, 1 shows an internal cross-sectional view of some components of the gear box 1. Fig.

The drill device 100 is constituted by a gear box 1 and a body casing 2, and the gear box 1 and the body casing 2 can be separated from each other. The upper casing member 3 may be coupled to the upper portion of the body casing 2 and the lower casing member 4 may be coupled to the lower portion of the body casing 2.

Referring to the internal cross-sectional view of the drilling apparatus 100, a ball bearing 2a is provided inside the body casing 2 of the drilling apparatus 100 and at the lower end of the upper casing member 3, A ball bearing (2a) is provided at the upper end of the casing member (4). Inside the body casing (2), a sleeve (5) is provided in contact with the ball bearing (2a). The sleeve 5 is provided with a drill shaft 8 therein. The drill shaft 8 is constituted by a first portion 8a provided with a screw 9 and a second portion 8b capable of fixing a drill bit 12 to be described later, 8) is coupled to the worm gears 11a, b to be described later.

On the other hand, a bevel gear shaft 9a is coupled to the lower end of the screw 9. A bevel gear 10 is coupled to the lower end of the bevel gear shaft 9a. The bevel gear 10 is constituted by a first bevel gear member 10a and a second bevel gear member 10b engaged with the first bevel gear member 10a. A bevel gear handle 17 is coupled to the first bevel gear member 10a. The second bevel gear member 10b can be engaged with the screw 9 through the bevel gear shaft 9a. That is, the bevel gear shaft 9a may be coupled to the second bevel gear member 10b, and the screw 9 may be coupled to the bevel gear shaft 9a. The bevel gear handle 17, the bevel gear 10, and the bevel gear shaft 9a are mounted on the gear box 1.

The rotational axis of the bevel gear handle 17 may be perpendicular to the direction in which the screw 9 extends (i.e., the rotational axis of the screw). When the bevel gear handle 17 is rotated in one direction, the first bevel gear member 10a coupled to the bevel gear handle 17 rotates together and the second bevel gear member 10a engaged with the first bevel gear member 10a The bevel gear shaft 9a coupled to the second bevel gear member 10b also rotates and the screw 9 coupled to the bevel gear shaft 9a also rotates.

The inner surface of the first portion 8a of the drill shaft 8 is formed into a female screw shape corresponding to the male screw shape of the screw 9, 9 and the inner wall of the first portion 8a of the drill shaft 8 are engaged with each other. When the screw 9 is rotated by the rotation of the bevel gear handle 17, the first portion 8a of the drill shaft 8 engaged with the male threaded outer surface of the screw 9 The inner surface moves along the outer surface of the male screw shape of the screw 9, so that the drill shaft 8 can advance. At this time, it advances based on the interval of the screw thread. For example, the screw thread spacing can be advanced by 1.25 mm per revolution. When the drill shaft 8 is advanced, the drill bit 12, which can be engaged with the second portion 8b of the drill shaft 8, can be moved to the place where the plugging in the pipe is deposited. When the bevel gear handle 17 is turned in the opposite direction, power is transmitted to the same components as described above and the drill shaft 8 is reversed.

When the length of the drilling apparatus 1 is 273 mm, for example, from the upper casing member 3 to the bevel gear handle 17 to be described later, the stroke distance of the up-and-down movement by the screw 9 is illustratively 135 mm to 140 mm Lt; / RTI > However, the present invention is not limited to this, and it is possible to adjust the stroke distance of the screw 9 in accordance with the environment of the process line in which the present invention is implemented, or to modify and change the size or shape of the drill 100 And it is possible to implement by adjusting the stroke distance of the screw 9 accordingly.

1a, the first part 8a of the drill shaft 8 surrounds the screw 9 and the second part 8b of the drill shaft 8 is provided with a drill bit 12 And can be inserted and fixed. At this time, a small groove (not shown) is provided in the second portion 8b of the drill shaft 8 and a convex portion (not shown) is provided in the drill blade 12, The drill bit 12 is fixed to the second portion 8b of the drill shaft 8 by engaging the convex portion of the drill bit 12 with the groove of the drill bit 8b. The worm gear handle 18 to be described later is rotated to rotate the drill shaft 8 so that the drill bit 12 is disengaged from the drill apparatus 100 even if the drill bit 12 coupled to the drill shaft 8 rotates So that the operator can work safely. The present invention is not limited to the above-described fixing method, and various modifications are possible.

When the bevel gear handle 17 is turned and the drill bit 12 reaches the operator's desired position, the operator turns the worm gear handle 18 to rotate the drill bit 12. Specifically, the worm gear handle 18 can be coupled to the first worm gear member 11a of the worm gear 11 and fixed thereto. The first worm gear member 11a is engaged with the second worm gear member 11b. When the worm gear handle 18 is rotated, the first worm gear member 11a rotates and the second worm gear member 11b meshes with the first worm gear member 11a. For example, when the worm gear handle 18 is turned clockwise, the second worm gear member 11b is rotated and brought into contact with the stationary plate 14 to the second worm gear member lib. As a result, the fixed plate 14 rotates in conjunction with the rotation of the second worm gear member 11b. Further, the shaft guide 13 coupled to the stationary plate 14 also rotates. Since the shaft guide 13 surrounds the drill shaft 8 and is in contact with the drill shaft 8, the rotation of the shaft guide 13 causes the drill shaft 8 contacting the drill shaft 8 to rotate as well. Further, the drill bit 12 coupled to the second portion 8b of the drill shaft 8 is also rotated. In other words, when the worm gear handle 18 is rotated, the first worm gear member 11a rotates, the second worm gear member 11b rotates while being engaged with the second worm gear member 11b, The drill shaft 8 is rotated by the rotational force of the shaft guide 13 and the drill bit 12 fixed to the drill shaft 8 rotates while the shaft guide 13 rotates, So that the plugging can be broken.

At this time, the sleeve 5 can also rotate with the rotation of the drill shaft 8. The ball bearings 2a provided between the sleeve 5 and the body casing 2 are connected to the sleeve 5, 13), and shock to the body casing 2 due to rotation of the drill bit 12 can be buffered.

On the other hand, for example, when the worm gear handle 18 is rotated in the counterclockwise direction, the second worm gear member 11b is rotated in the direction opposite to the above-described case, and the second worm gear member 11b is rotated 14, the fixing plate 14 and the drill shaft 8 are prevented from rotating. That is, it becomes a kind of gear neutral state. In this case, the drill shaft 8 is not affected by the worm gear handle 18 and the worm gear 11, so that only the influence of the up-down motion due to the rotation of the bevel gear handle 17 and the bevel gear 10 It becomes a state that can be. Therefore, when the worker attempts to adjust the position of the drill bit 12 up and down while performing the plugging operation, the worm gear handle 18 is turned counterclockwise at a predetermined number of revolutions so that the worm gear 11 is moved to the fixed plate 14 And then the bevel gear handle 17 is turned to adjust the positions of the shaft 8 and the drill blade 12 up and down.

When the worm gear handle 18 is rotated clockwise, the drill shaft 8 and the drill bit 12 are rotated, and when the worm gear handle 18 is rotated in the clockwise direction, the worm gear 11 is fixed The gear 14 is separated from the plate 14 to be in a kind of gear neutral state. However, the present invention is not limited to the above-described embodiment, but may be implemented in the opposite manner or may be modified or changed in various ways.

On the other hand, plugging in piping is in an environment of high temperature and pressure. Therefore, the broken plugging may fall and cause harm to the operator. Referring again to FIG. 1A, the drilling apparatus 100 includes an upper casing member 3 coupled to an upper portion of the body casing 2 so as to be contained in the upper casing member 3 even if the broken plugging falls downward. Respectively. In the upper casing member 3, a V packing 7 and a packing nut 6 to be described later are provided. The inner surface of the upper casing member 3 may be provided with a groove 3a capable of coupling the nipple 33 shown in FIG. 4B and the flexible high-pressure hose 31 shown in FIG. 4C . It is also possible to connect the upper casing member connecting pipe 41a and the valve 41b by placing the opening 3b in a part of the side surface of the upper casing member 3 as shown in Figs. 4B and 4C, The valve 41b can be opened and discharged to the outside of the drilling machine 100 through the upper casing member connecting pipe 41a during the operation. If necessary, an extension pipe may be connected to the upper casing member connecting pipe 41a and discharged to prevent the operator from reaching plugging.

A V packing 7 is provided between the drill shaft 8 and the sleeve 5 at the end of the shaft guide 13 at the upper side of the inner wall of the sleeve 5, 1a, and a packing nut 6 is provided at the upper end of the V-packing 7. As shown in Fig. The V packing 7 may be made of Teflon, for example, and the packing nut 6 may be made of stainless steel, for example. Thus, when the drill bit 12 is moved, the packing nut 6 transmits the load downward to press the V packing 7 having a small amount of elasticity with the Teflon material, and the urged V packing 7 is pressed So that the plugging held in the upper casing member 3 is inserted into the sleeve 5 or the body casing 2 even if the drill bit 12 is moved . The V packing 7 is configured such that the pressure in the upper casing member connecting pipe 41a is lower than the pressure in the upper casing member 3 when the plug member is connected by connecting the upper casing member connecting pipe 41a to the opening portion 3b of the upper casing member 3, So as not to be transmitted to the inside of the box 1, so that the operation of the gears installed in the gear box 1 is not affected.

Since the flexible high-pressure hose 31 of the drilling apparatus 100 of FIG. 4B and the nipple 33 of the drilling apparatus 100 according to the present invention of FIG. 4C are in the form of male threads, So that it can be coupled to the female-threaded portion. Accordingly, in the case of the drilling apparatus 100 according to the present invention of FIG. 4d, the drilling apparatus 100 can be longitudinally coupled to the lower portion of the processing apparatus of FIG. 3B. When the drilling apparatus 100 according to the present invention is tightly coupled to the processing apparatus, the valve shown in Fig. 3B is turned. When the valve is turned, the drill bit 12 of the drill apparatus 100 is opened so as to enter the piping of the processing apparatus. The bevel gear handle 17 of the drilling machine 100 is rotated to advance the drill bit 12 to the plugging position and rotate the drill bit to rotate the worm gear handle 18 as shown in Fig. .

Referring again to FIG. 4B, since the flexible wire 32 to which the drill bit 12 is connected and the flexible high-pressure hose 31 can be coupled to one end of the drilling apparatus 100, It is possible to connect the drilling apparatus 100 to a processing apparatus even in a space having a small height, for example, a height of 200 mm or less from the lower end of the processing apparatus to the floor, and thus the operator can easily work. The high-pressure hose 20 can withstand pressures of up to 30 Bar and temperatures up to 200 ° C, and the material can be made of, for example, stainless steel. The flexible wire 32 may be made of, for example, stainless steel. The flexible wire 32 may have a small groove at one end thereof and the drill bit 12 may have a convex portion to fix the flexible wire 32 and the drill bit 12. Similarly, the second portion 8b of the drill shaft 8 may have a small groove, and the other end of the flexible wire 32 is provided with a convex portion so that the flexible wire 32 is fixed to the drill shaft 8 You can also implement it. The drill bit 12 or the flexible wire 32 is rotated even if the shaft 8 is rotated by the worm gear handle 18 so that the flexible wire 32 connected to the drill bit 12 is rotated So that the worker can work safely without leaving the drilling machine 100.

Meanwhile, the drill bit 12 may be formed of a bronze material. Accordingly, since the drill bit 12 is made of a bronze material, it is possible to prevent the occurrence of sparks even when the flammable gas or liquid remains in the piping, thereby greatly reducing the risk of fire or explosion. In addition, the plugging deposited in the processing apparatus is solid, but has a smaller strength than the steel pipe, so that the plugging can be broken by the rotation of the drill bit 12, but the pipe can be prevented from being damaged.

Referring again to FIGS. 4B and 4D, a handle 42 is provided on the outer surface of the drilling apparatus 100. The bevel gear handle 17 and the worm gear handle 18 are provided in the drilling apparatus 100 according to the present invention. Therefore, the worker can carry out the plugging removal operation while holding the handle 42 with one hand while operating the bevel gear handle 17 or the worm gear handle 18 with the other hand. Alternatively, the worker may hold the bevel gear handle 17 with one hand and the worm gear handle 18 with the other hand.

The technical structure of the present invention described above is not limited to the above description and the drawings and the photographs, and various modifications are possible. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
